Some time ago we tried to find a browser extension that would display Google PageRank while we surf the web. Unfortunately, we've found that most third-party tools do not report PageRank correctly: their reports were different from the official report of Google Toolbar for many kinds of URLs (for example, URLs with hash, https URLs, URLs with blank spaces, etc). Additionally, those tools often reported a rank of 0 and no rank in the same way - rank of 0. At the same time, we didn't want to use Google Toolbar because it contains many features that we don't need, and it supports only a few browsers. Accordingly, we've decided to develop our own PageRank checker application.

PageRank for Chrome, Firefox, Safari, and Opera

PageRank is a browser extension that displays Google PageRank for the current page. The extension is available for Chrome, Firefox, Safari, and Opera. PageRank extension is fast, accurate, and lightweight.

Fast PageRank extension fetches information directly from Google servers, allowing for maximum possible speed. Every fetched result is also cached for one hour. The caching mechanism minimizes traffic and makes extension even faster.

Accurate Unlike similar applications, PageRank extension provides accurate results. Rank reported by PageRank is the same as rank reported by the official Google Toolbar.

Lightweight PageRank does only one thing and does it very well. It is lightweight and not overwhelmed by various unneeded features.

Functionality

Rank is displayed in the top right-hand corner of the browser as a number and a green bar. The number is displayed immediately, so there is no need to hover the mouse over the extension icon or click on it. When a user clicks on the extension icon, a popup is opened, and a table with ranks for all tabs is displayed in the popup.
